The purpose of this article is to establish overlay zoning districts wherein certain additional requirements are superimposed on the underlying standard zoning districts set forth in Article 2 of this chapter. Each overlay district is intended to address a special land use circumstance beyond those addressed by the underlying zoning district. Special requirements include mandatory protections against natural hazards, mandatory protections of valued natural resources, and special design guidelines. Each overlay district is intended to implement one or more aspects of the Comprehensive Plan and to ensure compliance with federal and state requirements.
A given property may lie within one or more overlay zoning districts based on its geographic location. The provisions of this article are intended to be consulted before issuance of any building permit, site plan approval, conditional use permit, zoning permit, zoning change, or land division to ensure the intended use meets all of the requirements of any applicable overlay district, in addition to the underlying standard zoning district (see Article 2). For each overlay district established in this article, a definition of the resource or geographic area is provided, followed by the specific purposes of the protective regulations governing the resource or geographic location, the method of delineating the boundaries of the overlay district, and the mandatory development regulations.
For the purpose of this chapter, the following overlay zoning districts are hereby established:
VCO
Village Center Design Overlay
SWO
Shoreland-Wetland Overlay
FWO
Floodway Overlay
FFO
Flood-Fringe Overlay
GFO
General Floodplain Overlay
EC
Environmental Conservation Overlay
PDO
Planned Development Overlay
Except where otherwise indicated in this article, the overlay zoning districts are represented on the Official Overlay Zoning Map, adopted and from time to time amended by the Village of Williams Bay.
A. 
Purpose. The Village Center Design Overlay District is intended to implement the design recommendations of the Village of Williams Bay Comprehensive Plan by preserving and enhancing the appearance, character, and property values of the community.
B. 
Overall Village Center Design theme. The design theme for the Village Center Design Overlay District shall be based on the Village's historic, pedestrian-oriented development pattern in its Village center, which incorporates a mixture of retail, service, residential, and institutional uses. Building orientation and character shall include minimal setbacks; one-, two-, and three-story structures; a mix of on-street and other off-site parking; and a focus on pedestrian-scaled design.
C. 
Design standards. All construction, including new structures, building additions, building alterations, and restorations or rehabilitations, shall meet the following design requirements. These requirements shall apply to all land uses located within the Village Center Design Overlay District except single-family homes.
(1)

These include "renovation review" and "site and design review," both described below.
(1) 
Renovation review. Applications for projects involving only a renovation of the exterior appearance of a structure (such as repainting; reroofing; re-siding; or replacing with identical colors, finishes, and materials), as determined by the Zoning Administrator, shall require Zoning Administrator review and approval. All necessary permits must be acquired.
(2) 
Site and design review. Applications involving any change in the exterior appearance or physical configuration of a property, including painting; roofing; siding; architectural component substitution; fencing; paving; installation of signage with different colors, finishes, or materials; grading; erection of a new building; demolition of an existing building; or the addition or removal of bulk to an existing building shall be subject to site and design review in accordance with the standard procedures applicable to all site plans per § 390-1206. The Village Board shall serve as the final discretionary review body and shall focus its review of the application on compliance with sound aesthetic, land use, site design, and economic revitalization practices. In part, this effort shall be guided by the Village's Comprehensive Plan and any other applicable downtown or special area plans.
(a) 
Site and design review proposals shall generally follow the procedures for site plan review (see § 390-1206).
(b) 
In addition to the standard application requirements for site plan review, applications shall be accompanied by a building permit application and the following information:
[1] 
A clear depiction of the existing appearance of the property. Clear color photographs are recommended for this purpose. Scaled and dimensioned drawings of existing components such as windows, doors, railings, fencing, or other site components, and/or detailed building elevations indicating the building's current appearance, may be required by the Village.
[2] 
A written description of the proposed project, including a complete listing of proposed components, materials, and colors.
[3] 
A clear depiction of the proposed appearance of the property. Paint charts, promotional brochures, and/or clear color photographs of replacement architectural components are recommended for this purpose. Scaled and dimensioned drawings of proposed components such as windows, doors, railings, fencing, or other site components, and/or detailed building elevations indicated the proposed alterations, may be required by the Village.
[4] 
Written justification for the proposed alteration consisting of the following:
[a] 
Reasons why the applicant believes the requested alteration is in harmony with the overall purpose and intent of the Village Center Design Overlay District; and
[b] 
Reasons why the applicant believes the requested alteration is consistent with the recommendations and forwards the objectives of the Village's Comprehensive Plan and other applicable Village planning documents; complements the design and layout of nearby buildings and developments in the Village Center Design Overlay District; and enhances, rather than detracts from, the desired character of the Village, and the Village Center in particular.
E. 
Penalty and appeals. Penalty for violation of the provisions of this section shall be per the provisions of § 390-1218. Appeals from the decisions of the Zoning Administrator, Plan Commission, and Village Board may be made per the provisions of this chapter and state statutes.
A. 
Statutory authorization. This Shoreland-Wetland Overlay Zoning District is adopted pursuant to the authorization in §§ 62.23, 61.351, 87.30 and 281.31, Wis. Stats.
B. 
Findings of fact and purpose. Uncontrolled use of the shoreland-wetlands and pollution of the navigable waters of the Village of Williams Bay would adversely affect the public health, safety, convenience, and general welfare and impair the tax base. The Legislature of Wisconsin has delegated responsibility to all municipalities to:
(1) 
Promote the public health, safety, convenience and general welfare;
(2) 
Maintain the storm and flood water storage capacity of wetlands;
(3) 
Prevent and control water pollution by preserving wetlands that filter or store sediments, nutrients, heavy metals or organic compounds that would otherwise drain into navigable waters;
(4) 
Protect fish, their spawning grounds, other aquatic life and wildlife by preserving wetlands and other aquatic habitat;
(5) 
Prohibit certain uses detrimental to the area regulated by this section; and
(6) 
Preserve shore cover and natural beauty by restricting the removal of natural shoreland cover and controlling shoreland-wetland excavation, filling and other earthmoving activities.
C. 
Compliance. The use of wetlands and the alteration of wetlands within the shoreland area of the Williams Bay shall be in full compliance with the terms of this Shoreland-Wetland Overlay District and other applicable local, state or federal regulations. (However, see Subsection R for standards applicable to nonconforming uses.)
D. 
Municipalities and state agencies regulated. Unless specifically exempted by law, all cities, villages, towns, and counties are required to comply with the provisions of this Shoreland-Wetland Overlay District and obtain all necessary permits. State agencies are required to comply if § 13.48(13), Wis. Stats., applies. The construction, reconstruction, maintenance and repair of state highways and bridges by the Wisconsin Department of Transportation are exempt when § 30.2022, Wis. Stats., applies.
E. 
Abrogation and greater restrictions.
(1) 
The provisions of this Shoreland-Wetland Overlay District supersede all the provisions of any municipal zoning code provisions enacted under § 61.35, 62.23 or 87.30, Wis. Stats., that relate to floodplains and shoreland-wetlands, except that where another provision in the Village of Williams Bay Zoning Code is more restrictive than this Shoreland-Wetland Overlay District, that provision shall continue in full force and effect to the extent of the greater restrictions, but not otherwise.
(2) 
This Shoreland-Wetland Overlay District is not intended to repeal, abrogate, or impair any existing deed restrictions, covenants or easements. However, where this Shoreland-Wetland Overlay District imposes greater restrictions, the provisions of this overlay district shall prevail.
F. 
Interpretation. In their interpretation and application, the provisions of this Shoreland-Wetland Overlay District shall be held to be minimum requirements and shall be liberally construed in favor of the municipality and shall not be deemed a limitation or repeal of any other powers granted by the Wisconsin Statutes. Where a provision of this overlay district is required by a standard in Ch. NR 117, Wis. Adm. Code, and where such provision is unclear, the provision shall be interpreted in light of the Chapter NR 117 standards in effect on the date of the adoption of the Shoreland-Wetland Overlay District provisions or in effect on the date of the most recent text amendment to this Shoreland-Wetland Overlay District section of this chapter.
G. 
Severability. Should any portion of this Shoreland-Wetland Overlay District be declared invalid or unconstitutional by a court of competent jurisdiction, the remainder of this overlay district shall not be affected.
H. 
Annexed areas. The county shoreland zoning provisions in effect on the date of annexation remain in effect administered by the Village of Williams Bay for all areas annexed by the Village of Williams Bay after May 7, 1982, unless any of the changes as allowed by § 59.692(7)(a)(1) to (3), Wis. Stats., occur.[1] These annexed lands are described on the Village of Williams Bay's Official Zoning Map. The county shoreland zoning provisions are incorporated by reference for the purpose of administering this section and are on file in the office of the Village of Williams Bay Clerk.

(a) 
Within 1,000 feet of the ordinary high-water mark of navigable lakes, ponds or flowages. Lakes, ponds or flowages in the municipality shall be presumed to be navigable if they are shown on the United States Geological Survey quadrangle maps or other zoning base maps that have been incorporated by reference and made a part of this section.
(b) 
Within 300 feet of the ordinary high-water mark of navigable rivers or streams, or to the landward side of the floodplain, whichever distance is greater. Rivers and streams shall be presumed to be navigable if they are designated as either continuous or intermittent waterways on the United States Geological Survey quadrangle maps or other zoning base maps that have been incorporated by reference and made a part of this section. Floodplain Zoning Maps adopted in § 390-0707D(2) shall be used to determine the extent of floodplain areas.
(2) 
The Shoreland-Wetland Overlay Zoning District also includes additional lowland areas and semi-lowland areas that may or may not fit within the technical definition of a wetland but that have been selected by the Village Board for protection.
K. 
Determinations of navigability and ordinary high-water mark location shall initially be made by the Zoning Administrator. When questions arise, the Zoning Administrator shall contact the appropriate district office of the Department of Natural Resources for a final determination of navigability or ordinary high-water mark.
L. 
When an apparent discrepancy exists between the Shoreland-Wetland Overlay District boundary shown on the Official Zoning Map and actual field conditions at the time the Official Zoning Map was adopted, the Zoning Administrator shall contact the appropriate district office of the Department of Natural Resources to determine if the Shoreland-Wetland Overlay District boundary, as mapped, is in error. If Department of Natural Resources staff concur with the Zoning Administrator that a particular area was incorrectly mapped as a wetland, the Zoning Administrator shall have the authority to immediately grant or deny a zoning permit in accordance with the regulations applicable to the correct underlying base zoning district. In order to correct wetland mapping errors or acknowledge exempted wetlands designated in Subsections M and N, the Zoning Administrator shall be responsible for initiating a map amendment within a reasonable period.
M. 
Filled wetlands. Wetlands that are filled prior to the date on which the municipality received final wetland inventory maps, in a manner that affects their wetland characteristics to the extent that the area can no longer be defined as wetland, are not subject to the provisions of this Shoreland-Wetland Overlay District.

The word "shall" is mandatory, not permissive. All distances, unless otherwise specified, shall be measured horizontally. Where the same or similar term is defined differently in § 390-0114 of this chapter, or in any other section of this chapter, than in this § 390-0706, the definition provided in this section shall apply to all Shoreland-Wetland Overlay District provisions and the definition provided in § 390-0114 shall apply to all other sections of this chapter.
(2) 
As used in this section, the following terms shall have the meanings indicated:
ACCESSORY STRUCTURE OR USE
A detached subordinate structure or a use that is clearly incidental to, and customarily found in connection with, the principal structure or use to which it is related and which is located on the same lot as that of the principal structure or use.
BOATHOUSE
A permanent structure used for the storage of watercraft and associated materials and includes all structures that are totally enclosed, have roofs or walls, or any combination of structural parts.
[Amended at time of adoption of Code (see Ch. 1, General Provisions, Art. II)]
CLASS 2 PUBLIC NOTICE
Publication of a public hearing notice under Ch. 985, Wis. Stats., in a newspaper of circulation in the affected area. Publication is required on two consecutive weeks, the last at least seven days prior to the hearing.
CONDITIONAL USE
A use that is allowed by the Shoreland-Wetland Overlay District provisions, provided that certain conditions specified in this section are met and that a permit is granted by the Village Board.
DEVELOPMENT
Any man-made change to improved or unimproved real estate, including, but not limited to, the construction of buildings, structures or accessory structures; the construction of additions or substantial alterations to buildings, structures, or accessory structures; the placement of buildings or structures; ditching, lagooning, dredging, filling, grading, paving, excavation, or drilling operations; and the deposition or extraction of earthen materials.
DRAINAGE SYSTEM
One or more artificial ditches, tile drains, or similar devices that collect surface runoff or groundwater and convey it to a point of discharge.
ENVIRONMENTAL CONTROL FACILITY
Any facility, temporary or permanent, that is reasonably expected to abate, reduce, or aid in the prevention, measurement, control, or monitoring of noise, air, or water pollutants, solid waste and thermal pollution, radiation, or other pollutants, including facilities installed principally to supplement or to replace existing property or equipment not meeting or allegedly not meeting acceptable pollution control standards or that are to be supplemented or replaced by other pollution control facilities.
FIXED HOUSEBOAT
As defined in § 30.01(1r), Wis. Stats., means a structure not actually used for navigation that extends beyond the ordinary high-water mark of a navigable waterway and is retained in place either by cables to the shoreline or by anchors or spud poles attached to the bed of the waterway.
NAVIGABLE WATERS
(a) 
Lake Superior, Lake Michigan, all natural inland lakes within Wisconsin, and all streams, ponds, sloughs, flowages, and other waters within the territorial limits of this state, including the Wisconsin portion of the boundary waters, which are navigable under the laws of this state. Under § 281.31(2m), Wis. Stats., notwithstanding any other provision of law or administrative rule promulgated thereunder, shoreland ordinances required under § 61.351, Wis. Stats., and Ch. NR 117, Wis. Adm. Code, do not apply to lands adjacent to farm drainage ditches if any of the following apply:
[1] 
Such lands are not adjacent to a natural navigable stream or river;
[2] 
Those parts of such drainage ditches adjacent to such lands were not navigable streams before ditching; and
[3] 
Such lands are maintained in nonstructural agricultural use.
(b) 
Wisconsin's Supreme Court has declared navigable bodies of water that have a bed differentiated from adjacent uplands and levels or flow sufficient to support navigation by a recreational craft of the shallowest draft on an annually recurring basis [Muench v. Public Service Commission, 261 Wis. 492 (1952) and DeGaynor and Co., Inc., v. Department of Natural Resources, 70 Wis. 2d 936 (1975)]. For example, a stream that is navigable by skiff or canoe during normal spring high water is navigable, in fact, under the laws of this state though it may be dry during other seasons.
ORDINARY HIGH-WATER MARK
The point on the bank or shore up to which the presence and action of surface water is so continuous as to leave a distinctive mark such as by erosion, destruction or prevention of terrestrial vegetation, predominance of aquatic vegetation, or other easily recognized characteristic.
SHORELANDS
Lands within the following distances from the ordinary high-water mark of navigable waters: 1,000 feet from a lake, pond or flowage and 300 feet from a river or stream or to the landward side of the floodplain, whichever distance is greater.
WETLAND ALTERATION
Any filling, flooding, draining, dredging, ditching, tiling, excavating, temporary water level stabilization measures, or dike and dam construction in a wetland area.
WETLANDS
Those areas where water is at, near, or above the land surface long enough to support aquatic or hydrophytic vegetation and that have soils indicative of wet conditions.
[Amended 3-16-2022 by Ord. No. 2022-02]
A. 
Statutory authorization. This section is adopted pursuant to the authorization in §§ 61.35 and 62.23, Wis. Stats., for villages and cities, and the requirements in § 87.30, Wis. Stats.
B. 
Finding of fact. Uncontrolled development and use of the floodplains and rivers of this municipality would impair the public health, safety, convenience, general welfare and tax base.
C. 
Statement of purpose. This section is intended to regulate floodplain development to:
(1) 
Protect life, health and property;
(2) 
Minimize expenditures of public funds for flood control projects;
(3) 
Minimize rescue and relief efforts undertaken at the expense of the taxpayers;
(4) 
Minimize business interruptions and other economic disruptions;
(5) 
Minimize damage to public facilities in the floodplain;
(6) 
Minimize the occurrence of future flood blight areas in the floodplain;
(7) 
Discourage the victimization of unwary land and homebuyers;
(8) 
Prevent increases in flood heights that could increase flood damage and result in conflicts between property owners; and
(9) 
Discourage development in a floodplain if there is any practicable alternative to locate the activity, use or structure outside of the floodplain.
D. 
Title. This section shall be known as the "Floodplain Zoning Ordinance for the Village of Williams Bay, Wisconsin."
E. 
General provisions.
(1) 
Areas to be regulated. This section regulates all areas of special flood hazard identified as Zones A, AO, AH, A1-30, and AE on the Flood Insurance Rate Map. Additional areas identified on maps approved by the Department of Natural Resources (DNR) and local community may also be regulated under the provisions of this section, where applicable.
(2) 
Official maps and revisions. Special flood hazard areas (SFHA) are designated as Zones A, A1-30, AE, AH, and AO on the Flood Insurance Rate Maps (FIRMs) based on flood hazard analyses summarized in the Flood Insurance Study (FIS) listed in Subsection E(2)(a) below. Additional flood hazard areas subject to regulation under this section are identified on maps based on studies approved by the DNR and listed in Subsection E(2)(b) below. These maps and revisions are on file in the office of the Village Clerk, Village of Williams Bay, WI.
(a) 
Official maps based on the Flood Insurance Study (FIS):
[1] 
Flood Insurance Rate Map (FIRM), panel numbers 55127C0304E, dated September 3, 2014, and 55127C0308D and 55127C0310D, dated October 2, 2009.
[2] 
Flood Insurance Study (FIS) for Walworth County, volumes 55127CV001C and 55127CV002C, dated April 6, 2022.
[3] 
Approved by the DNR and FEMA.
(b) 
Official maps based on other studies. Any maps referenced in this section must be approved by the DNR and be more restrictive than those based on the FIS at the site of the proposed development.
[1] 
Walworth County and Incorporated Areas Flood Storage Districts, Panel 14, dated April 6, 2022.
[2] 
Walworth County and Incorporated Areas Flood Storage Districts, Panel 15, dated April 6, 2022.
[3] 
Approved by the DNR.
F. 
Establishment of floodplain zoning districts. The flood hazard areas regulated by this section are divided into districts as follows:
(1) 
The Floodway Overlay District (FWO) is the channel of a river or stream and those portions of the floodplain adjoining the channel required to carry the regional floodwaters, within AE Zones as shown on the FIRM, or within A Zones shown on the FIRM when determined according to Subsection S(5).
(2) 
The Flood Fringe Overlay District (FFO) is that portion of a riverine special flood hazard area outside the floodway within AE Zones on the FIRM, or, when floodway limits have been determined according to Subsection S(5), within A Zones shown on the FIRM.
(3) 
The General Floodplain Overlay District (GFO) is those riverine areas that may be covered by floodwater during the regional flood in which a floodway boundary has not been delineated on the FIRM and also includes shallow flooding areas identified as AH and AO Zones on the FIRM.
(4) 
The Flood Storage Overlay District (FSO) is that area of the floodplain where storage of floodwaters is calculated to reduce the regional flood discharge.
G. 
Locating floodplain boundaries. Discrepancies between the exterior boundaries of Zones A1-30, AE, AH, or A on the official floodplain zoning map and actual field conditions may be resolved using the criteria in Subsection G(1) or (2) below. If a significant difference exists, the map shall be amended according to Subsection W, Amendments. The Zoning Administrator can rely on a boundary derived from a profile elevation to grant or deny a land use permit, whether or not a map amendment is required. The Zoning Administrator shall be responsible for documenting actual pre-development field conditions and the basis upon which the district boundary was determined. Disputes between the Zoning Administrator and an applicant over the district boundary line shall be settled according to Subsection V(6) and the criteria in Subsection G(1) and (2) below. Where the flood profiles are based on established base flood elevations from a FIRM, FEMA must approve any map amendment or revision pursuant to Subsection W, Amendments.
(1) 
If flood profiles exist, the map scale and the profile elevations shall determine the district boundary. The regional or base flood elevations shall govern if there are any discrepancies.
(2) 
Where flood profiles do not exist for projects, including any boundary of Zone A or AO, the location of the boundary shall be determined by the map scale.
H. 
Removal of lands from floodplain.
(1) 
Compliance with the provisions of this section shall not be grounds for removing land from the floodplain unless it is filled at least two feet above the regional or base flood elevation, the fill is contiguous to land outside the floodplain, and the map is amended pursuant to Subsection W, Amendments.
(2) 
The delineation of any of the floodplain districts may be revised by the community where natural or man-made changes have occurred and/or where more detailed studies have been conducted. However, prior to any such change, approval must be obtained from the Wisconsin Department of Natural Resources and Federal Emergency Management Agency. A completed letter of map revision is a record of this approval. The Floodplain Administrator shall not sign a community acknowledgment form unless all criteria set forth in the following subsections are met:
(a) 
The land and/or land around the structure must be filled at least two feet above the regional or base flood elevation;
(b) 
The fill must be contiguous to land outside the floodplain; the applicant shall obtain a floodplain development permit before applying for a LOMR or LOMR-F.
(3) 
Removal of lands from the floodplain may also occur by operation of § 87.30(1)(e), Wis. Stats., if a property owner has obtained a letter of map amendment from the Federal Emergency Management Agency under 44 CFR 70.
I. 
Compliance.
(1) 
No structure or use within areas regulated by this section shall hereafter be located, erected, constructed, reconstructed, repaired, extended, converted, enlarged, or altered without full compliance with the terms of this section and all other applicable regulations that apply to uses within the jurisdiction of this section.
(2) 
Failure to obtain a floodplain development permit shall be a violation of this section and shall be punishable in accordance with Subsection X.
(3) 
Floodplain development permits issued on the basis of plans and applications approved by the Floodplain Administrator authorize only the use, and arrangement, set forth in such approved plans and applications, or amendments thereto if approved by the Floodplain Administrator. Use, arrangement, or construction contrary to that authorized shall be deemed a violation of this section and punishable in accordance with Subsection X.
J. 
Municipalities and state agencies regulated. Unless specifically exempted by law, all cities, villages, towns, and counties are required to comply with this section and obtain all necessary permits. State agencies are required to comply if § 13.48(13), Wis. Stats., applies. The construction, reconstruction, maintenance and repair of state highways and bridges by the Wisconsin Department of Transportation is exempt when § 30.2022, Wis. Stats., applies. Although exempt from a local zoning permit and permit fees, the DOT must provide sufficient project documentation and analysis to ensure that the community is in compliance with federal, state, and local floodplain standards.
K. 
Abrogation and greater restrictions.
(1) 
This section supersedes all the provisions of any municipal zoning ordinance enacted under § 61.35, Wis. Stats., for villages; or § 87.30, Wis. Stats., which relate to floodplains. A more restrictive ordinance shall continue in full force and effect to the extent of the greater restrictions, but not otherwise.
(2) 
This section is not intended to repeal, abrogate or impair any existing deed restrictions, covenants or easements. If this section imposes greater restrictions, the provisions of this section shall prevail.
L. 
Interpretation. In their interpretation and application, the provisions of this section are the minimum requirements liberally construed in favor of the governing body and are not a limitation on or repeal of any other powers granted by the Wisconsin Statutes. If a provision of this section, required by Ch. NR 116, Wis. Adm. Code, is unclear, the provision shall be interpreted in light of the standards in effect on the date of the adoption of this section or in effect on the date of the most recent text amendment to this section.
M. 
Warning and disclaimer of liability. The flood protection standards in this section are based on engineering experience and research. Larger floods may occur, or the flood height may be increased by man-made or natural causes. This section does not imply or guarantee that non-floodplain areas or permitted floodplain uses will be free from flooding and flood damages. This section does not create liability on the part of, or a cause of action against, the municipality or any officer or employee thereof for any flood damage that may result from reliance on this section.
N. 
Severability. Should any portion of this section be declared unconstitutional or invalid by a court of competent jurisdiction, the remainder of this section shall not be affected.
O. 
Annexed areas. The Walworth County floodplain zoning provisions in effect on the date of annexation shall remain in effect and shall be enforced by the Village of Williams Bay for all annexed areas until the Village adopts and enforces an ordinance which meets the requirements of Ch. NR 116, Wis. Adm. Code, and 44 CFR 59-72, National Flood Insurance Program (NFIP). These annexed lands are described on the Village's Official Zoning Map. County floodplain zoning provisions are incorporated by reference for the purpose of administering this section and are on file in the office of the Village Zoning Administrator. All plats or maps of annexation shall show the regional flood elevation and the floodway location.
P. 
General standards applicable to all floodplain districts. The community shall review all permit applications to determine whether proposed building sites will be reasonably safe from flooding and assure that all necessary permits have been received from those governmental agencies whose approval is required by federal or state law.
(1)

(a) 
Be designed and anchored to prevent flotation, collapse, or lateral movement of the structure resulting from hydrodynamic and hydrostatic loads, including the effects of buoyancy;
(b) 
Be constructed with flood-resistant materials;
(c) 
Be constructed by methods and practices that minimize flood damages; and
(d) 
Be constructed with electrical, heating, ventilation, plumbing, and air conditioning equipment and other service facilities that are designed and/or located so as to prevent water from entering or accumulating within the components during conditions of flooding.
(2) 
If a subdivision or other proposed new development is in a flood-prone area, the community shall assure that:
(a) 
Such proposed subdivision or other proposed new development is consistent with the need to minimize flood damage within the flood-prone area;
(b) 
Public utilities and facilities, such as sewer, gas, electrical, and water systems, are located and constructed to minimize or eliminate flood damage; and
(c) 
Adequate drainage is provided to reduce exposure to flood hazards.
(d) 
All subdivision proposals (including manufactured home parks) shall include regional flood elevation and floodway data for any development that meets the "subdivision" definition of this section and all other requirements in Subsection V(2).
(3) 
Hydraulic and hydrologic analyses.
(a) 
No floodplain development shall:
[1] 
Obstruct flow, defined as development which blocks the conveyance of floodwaters by itself or with other development, causing any increase in the regional flood height; or
[2] 
Cause any increase in the regional flood height due to floodplain storage area lost.
(b) 
The Zoning Administrator shall deny permits if it is determined the proposed development will obstruct flow or cause any increase in the regional flood height, based on the officially adopted FIRM or other adopted map, unless the provisions of Subsection W, Amendments, are met.
(4) 
Watercourse alterations. No land use permit to alter or relocate a watercourse in a mapped floodplain shall be issued until the local official has notified, in writing, all adjacent municipalities, the Department and FEMA regional offices, and required the applicant to secure all necessary state and federal permits. The standards of Subsection P(3) must be met and the flood carrying capacity of any altered or relocated watercourse shall be maintained. As soon as is practicable, but not later than six months after the date of the watercourse alteration or relocation and pursuant to Subsection W, Amendments, the community shall apply for a letter of map revision (LOMR) from FEMA. Any such alterations must be reviewed and approved by FEMA and the DNR through the LOMC process.
(5) 
Chapters 30 and 31, Wis. Stats., development. Development which requires a permit from the Department, under Chs. 30 and 31, Wis. Stats., such as docks, piers, wharves, bridges, culverts, dams and navigational aids, may be allowed if the necessary permits are obtained and amendments to the Floodplain Zoning Ordinance are made according to Subsection W, Amendments.

This procedure shall include a written agreement between the campground owner, the municipal emergency government coordinator and the chief law enforcement official which specifies the flood elevation at which evacuation shall occur, personnel responsible for monitoring flood elevations, types of warning systems to be used and the procedures for notifying at-risk parties, and the methods and personnel responsible for conducting the evacuation;
(e) 
This agreement shall be for no more than one calendar year, at which time the agreement shall be reviewed and updated, by the officials identified in Subsection P(6)(d), to remain in compliance with all applicable regulations, including those of the State Department of Agriculture, Trade and Consumer Protection and all other applicable regulations;
(f) 
All mobile recreational vehicles placed on the site must meet one of the following:
[1] 
Only camping units that are fully licensed, if required, and ready for highway use are allowed; or
[2] 
The camping units shall not occupy any site in the campground for more than 180 consecutive days, at which time the camping unit must be removed from the floodplain for a minimum of 24 hours.
[3] 
A mobile recreational vehicle is ready for highway use if it is on its wheels or jacking system, is attached to the site only by quick-disconnect utilities and security devices and has no permanently attached additions.
(g)

S. 
General Floodplain Overlay District (GFO).
(1) 
Applicability. The provisions for the General Floodplain District shall apply to development in all floodplains mapped as A, AO, AH, and in AE Zones within which a floodway is not delineated on the Flood Insurance Rate Maps identified in Subsection E(2)(a).
(2) 
Floodway boundaries. For proposed development in Zone A, or in Zone AE within which a floodway is not delineated on the Flood Insurance Rate Map identified in Subsection E(2)(a), the boundaries of the regulatory floodway shall be determined pursuant to Subsection S(5). If the development is proposed to encroach upon the regulatory floodway, the development is subject to the standards of Subsection Q. If the development is located entirely within the flood fringe, the development is subject to the standards of Subsection R.
(3) 
Permitted uses. Pursuant to Subsection S(5), it shall be determined whether the proposed use is located within the floodway or flood fringe. Those uses permitted in the Floodway [Subsection Q(2)] and Flood Fringe [Subsection R(2)] Districts are allowed within the General Floodplain District, according to the standards of Subsection S(4), provided that all permits or certificates required under Subsection V(1) have been issued.
(4)

T. 
Flood Storage Overlay District. The Flood Storage Overlay District delineates that portion of the floodplain where storage of floodwaters has been taken into account and is relied upon to reduce the regional flood discharge. The district protects the flood storage areas and assures that any development in the storage areas will not decrease the effective flood storage capacity which would cause higher flood elevations.
(1) 
Applicability. The provisions of this subsection apply to all areas within the Flood Storage District (FSD), as shown on the official floodplain zoning maps.
(2) 
Permitted uses. Any use or development which occurs in a Flood Storage District must meet the applicable requirements in Subsection R(3).
(3) 
Standards for development in Flood Storage Overlay Districts.
(a) 
Development in a Flood Storage Overlay District shall not cause an increase equal or greater than 0.00 of a foot in the height of the regional flood.
(b) 
No development shall be allowed which removes flood storage volume unless an equal volume of storage as defined by the pre-development ground surface and the regional flood elevation shall be provided in the immediate area of the proposed development to compensate for the volume of storage which is lost (compensatory storage). Excavation below the groundwater table is not considered to provide an equal volume of storage.
(c) 
If compensatory storage cannot be provided, the area may not be developed unless the entire area zoned as Flood Storage Overlay District, on this waterway, is rezoned to the Flood Fringe Overlay District. This must include a revision to the floodplain study and map done for the waterway to revert to the higher regional flood discharge calculated without floodplain storage, as per Subsection W, Amendments, of this section.
(d) 
No area may be removed from the Flood Storage Overlay District unless it can be shown that the area has been filled to the flood protection elevation and is contiguous to other lands lying outside of the floodplain.
U. 
Nonconforming uses.
(1) 
General.
(a) 
Applicability.
[1] 
The standards in this subsection shall apply to all uses and buildings that do not conform to the provisions contained within a floodplain zoning ordinance or with § 87.30, Wis. Stats., and §§ NR 116.12-14, Wis. Adm. Code, and 44 CFR 59-72. These standards shall apply to all modifications or additions to any nonconforming use or structure and to the use of any structure or premises which was lawful before the passage of this section or any amendment thereto. A party asserting existence of a lawfully established nonconforming use or structure has the burden of proving that the use or structure was compliant with the floodplain zoning ordinance in effect at the time the use or structure was created.
[2] 
As permit applications are received for additions, modifications, or substantial improvements to nonconforming buildings in the floodplain, municipalities shall develop a list of those nonconforming buildings, their present equalized assessed value and a list of the costs of those activities associated with changes to those buildings.
(b) 
The existing lawful use of a structure or its accessory use which is not in conformity with the provisions of this section may continue subject to the following conditions:
[1] 
No modifications or additions to a nonconforming use or structure shall be permitted unless they comply with this section. The words "modification" and "addition" include, but are not limited to, any alteration, addition, modification, structural repair, rebuilding or replacement of any such existing use, structure or accessory structure or use. Maintenance is not considered a modification; this includes painting, decorating, paneling and other nonstructural components and the maintenance, repair or replacement of existing private sewage or water supply systems or connections to public utilities. Any costs associated with the repair of a damaged structure are not considered maintenance. The construction of a deck that does not exceed 200 square feet and that is adjacent to the exterior wall of a principal structure is not an extension, modification or addition. The roof of the structure may extend over a portion of the deck in order to provide safe ingress and egress to the principal structure.
[2] 
If a nonconforming use or the use of a nonconforming structure is discontinued for 12 consecutive months, it is no longer permitted and any future use of the property, and any structure or building thereon, shall conform to the applicable requirements of this section.
[3] 
The municipality shall keep a record which lists all nonconforming uses and nonconforming structures, their present equalized assessed value, the cost of all modifications or additions which have been permitted, and the percentage of the structure's total current value those modifications represent.
[4] 
No modification or addition to any nonconforming structure or any structure with a nonconforming use, which over the life of the structure would equal or exceed 50% of its present equalized assessed value, shall be allowed unless the entire structure is permanently changed to a conforming structure with a conforming use in compliance with the applicable requirements of this section. Contiguous dry land access must be provided for residential and commercial uses in compliance with Subsection R(3)(a). The costs of elevating the lowest floor of a nonconforming building or a building with a nonconforming use to the flood protection elevation are excluded from the 50% provisions of this subsection.
[5] 
No maintenance on a per-event basis to any nonconforming structure or any structure with a nonconforming use, the cost of which would equal or exceed 50% of its present equalized assessed value, shall be allowed unless the entire structure is permanently changed to a conforming structure with a conforming use in compliance with the applicable requirements of this section. Contiguous dry land access must be provided for residential and commercial uses in compliance with Subsection R(3)(a). Maintenance to any nonconforming structure, which does not exceed 50% of its present equalized assessed value on a per-event basis, does not count against the cumulative calculations over the life of the structure for substantial improvement calculations.
[6] 
If on a per-event basis the total value of the work being done under Subsection U(1)(b)[4] and [5] equals or exceeds 50% of the present equalized assessed value, the work shall not be permitted unless the entire structure is permanently changed to a conforming structure with a conforming use in compliance with the applicable requirements of this section. Contiguous dryland access must be provided for residential and commercial uses in compliance with Subsection R(3)(a).
[7] 
Except as provided in Subsection U(1)(b)[8], if any nonconforming structure or any structure with a nonconforming use is destroyed or is substantially damaged, it cannot be replaced, reconstructed or rebuilt unless the use and the structure meet the current section requirements. A structure is considered substantially damaged if the total cost to restore the structure to its pre-damaged condition equals or exceeds 50% of the structure's present equalized assessed value.
[8] 
For nonconforming buildings that are substantially damaged or destroyed by a nonflood disaster, the repair or reconstruction of any such nonconforming building shall be permitted in order to restore it to the size and use in effect prior to the damage event, provided that the following minimum requirements are met and all required permits have been granted prior to the start of construction:
[a] 
Residential structures:
[i] 
Shall have the lowest floor, including basement, elevated to or above the flood protection elevation using fill, pilings, columns, posts or perimeter walls. Perimeter walls must meet the requirements of Subsection V(8)(b).
[ii] 
Shall be anchored to prevent flotation, collapse, or lateral movement of the structure resulting from hydrodynamic and hydrostatic loads, including the effects of buoyancy, and shall be constructed with methods and materials resistant to flood damage.
[iii] 
Shall be constructed with electrical, heating, ventilation, plumbing and air conditioning equipment and other service facilities that are designed and/or elevated so as to prevent water from entering or accumulating within the components during conditions of flooding.
[iv] 
In A Zones, obtain, review and utilize any flood data available from a federal, state or other source.
[v] 
In AO Zones with no elevations specified, shall have the lowest floor, including basement, meet the standards in Subsection S(4).
[vi] 
In AO Zones, shall have adequate drainage paths around structures on slopes to guide floodwaters around and away from the structure.
[b] 
Nonresidential structures:
[i] 
Shall meet the requirements of Subsection U(1)(b)[8][a][i] through [vi].
[ii] 
Shall either have the lowest floor, including basement, elevated to or above the regional flood elevation, or, together with attendant utility and sanitary facilities, shall meet the standards in Subsection V(8)(a) or (b).
[iii] 
In AO Zones with no elevations specified, shall have the lowest floor, including basement, meet the standards in Subsection S(4).
(c) 
A nonconforming historic structure may be altered if the alteration will not preclude the structure's continued designation as an historic structure, the alteration will comply with Subsection Q(3)(a), flood-resistant materials are used, and construction practices and floodproofing methods that comply with Subsection V(8) are used. Repair or rehabilitation of historic structures shall be exempt from the development standards of Subsection U(1)(b)[8][a] if it is determined that the proposed repair or rehabilitation will not preclude the structure's continued designation as an historic structure and is the minimum necessary to preserve the historic character and design of the structure.
(2) 
Floodway Overlay District.
(a) 
No modification or addition shall be allowed to any nonconforming structure or any structure with a nonconforming use in the Floodway Overlay District, unless such modification or addition:
[1] 
Has been granted a permit or variance which meets all ordinance requirements;
[2] 
Meets the requirements of Subsection U(1);
[3] 
Shall not increase the obstruction to flood flows or regional flood height;
[4] 
Any addition to the existing structure shall be floodproofed, pursuant to Subsection V(8), by means other than the use of fill, to the flood protection elevation; and
[5] 
If any part of the foundation below the flood protection elevation is enclosed, the following standards shall apply:
[a] 
The enclosed area shall be designed by a registered architect or engineer to allow for the efficient entry and exit of floodwaters without human intervention. A minimum of two openings must be provided with a minimum net area of at least one square inch for every one square foot of the enclosed area. The lowest part of the opening can be no more than 12 inches above the adjacent grade;
[b]

The area included in a FDP may be only a portion of the area included in a previously approved GDP.
(3) 
The Plan Commission or Village Board may specify other plans, documents, or schedules that must be submitted prior to consideration or approval of the FDP, as such may be relevant to review.
(4) 
Approval of a FDP shall involve the same procedures necessary for the approval of a site plan, as described under § 390-1206 of this chapter.
(5) 
All portions of an approved Planned Development FDP not fully developed within five years of final Village Board approval shall expire, and no additional development shall be allowed. The Village Board may extend this five-year period by an additional five years via a majority vote following a public hearing and recommendation by the Plan Commission. Completed portions of the Planned Development FDP shall retain the planned development status.

Criteria for approval. In its review and action an application for a Planned Development Overlay District, the Plan Commission and, subsequently, the Village Board shall make findings with respect to the following criteria:
(1) 
The proposed planned development project is consistent with the overall purpose and intent of this chapter.
(2) 
The proposed planned development project is consistent with the Village's Comprehensive Plan (it is the responsibility of the Village to determine such consistency).
(3) 
The proposed planned development project would maintain the desired relationships between land uses, land use densities and intensities, and land use impacts in the environs of the subject site.
(4) 
Adequate public infrastructure is or will be available to accommodate the range of uses being proposed for the planned development project, including but not limited to public sewer and water and public roads.
(5) 
The proposed planned development project will incorporate appropriate and adequate buffers and transitions between areas of different land uses and development densities/intensities.
(6) 
The proposed planned development project design does not detract from areas of natural beauty surrounding the site.
(7) 
The proposed architecture and character of the proposed planned development project is compatible with adjacent/nearby development.
(8) 
The proposed planned development project will positively contribute to the physical appearance and functional arrangement of development in the area.
(9) 
The proposed planned development project will produce significant benefits in terms of environmental design and significant alternative approaches to addressing development performance that relate to and more than compensate for any requested exemption or variation of any normal standard of this chapter.
(10) 
For planned development projects that are proposed to be developed in phases, the applicant can provide a clear timeline for development and can demonstrate that the project would be successful even if all phases were not or could not be completed.
